Objectives: Decrements in cognitive function may already be evident in young children with type 1 diabetes (T1D). Here we report prospectively acquired cognitive results over 18 months in a large cohort of young children with and without T1D. Methods: A total of 144 children with T1D (mean HbA1c: 7.9%) and 70 age-matched healthy controls (mean age both groups 8.5 years; median diabetes duration 3.9 years; mean age of onset 4.1 years) underwent neuropsychological testing at baseline and after 18-months of follow-up. We hypothesized that group differences observed at baseline would be more pronounced after 18 months, particularly in those T1D patients with greatest exposure to glycemic extremes. Results: Cognitive domain scores did not differ between groups at the 18 month testing session and did not change differently between groups over the follow-up period. However, within the T1D group, a history of diabetic ketoacidosis (DKA) was correlated with lower Verbal IQ and greater hyperglycemia exposure (HbA1c area under the curve) was inversely correlated to executive functions test performance. In addition, those with a history of both types of exposure performed most poorly on measures of executive function. Conclusions: The subtle cognitive differences between T1D children and nondiabetic controls observed at baseline were not observed 18 months later. Within the T1D group, as at baseline, relationships between cognition (Verbal IQ and executive functions) and glycemic variables (chronic hyperglycemia and DKA history) were evident. Continued longitudinal study of this T1D cohort and their carefully matched healthy comparison group is planned. (JINS, 2016, 21, 293–302)

The aim of this study was to assess cognitive functioning in children with type 1 diabetes (T1D) and examine whether glycemic history influences cognitive function. Neuropsychological evaluation of 216 children (healthy controls, n = 72; T1D, n = 144) ages 4–10 years across five DirecNet sites. Cognitive domains included IQ, Executive Functions, Learning and Memory, and Processing Speed. Behavioral, mood, parental IQ data, and T1D glycemic history since diagnosis were collected. The cohorts did not differ in age, gender or parent IQ. Median T1D duration was 2.5 years and average onset age was 4 years. After covarying age, gender, and parental IQ, the IQ and the Executive Functions domain scores trended lower (both p = .02, not statistically significant adjusting for multiple comparisons) with T1D relative to controls. Children with T1D were rated by parents as having more depressive and somatic symptoms (p < .001). Learning and memory (p = .46) and processing speed (p = .25) were similar. Trends in the data supported that the degree of hyperglycemia was associated with Executive Functions, and to a lesser extent, Child IQ and Learning and Memory. Differences in cognition are subtle in young children with T1D within 2 years of onset. Longitudinal evaluations will help determine whether these findings change or become more pronounced with time.

The role of total thyroidectomy in the management of patients with Graves' disease remains controversial. However, there is increasing evidence to support the role of the procedure as a safe and definitive treatment for Graves' disease.

Method:

Patients were identified from a prospective thyroid database of the multidisciplinary thyroid clinic at Hull Royal Infirmary. All case notes were independently reviewed to confirm the data held on the database.

Results:

Over a 7-year period, the senior author has performed 206 total thyroidectomies for Graves' disease. The incidence of temporary recurrent laryngeal nerve palsy and hypoparathyroidism was 3.4 per cent and 24 per cent respectively. There was one case of permanent unilateral recurrent laryngeal nerve palsy, and 3.9 per cent of patients developed permanent hypoparathyroidism. There has been no relapse of thyrotoxicosis.

Conclusion:

In the context of a multidisciplinary thyroid clinic, total thyroidectomy should be offered as a safe and effective first-line treatment option for Graves' disease.

A total of 220 primary procedures were conducted over 4.5 years. Data were not available for 16 patients. Thirteen procedures (6.4 per cent) were considered failures, and these cases were individually reviewed and classified according to the reason for failure.

Conclusion:

Establishing the cause of failure following surgery for primary hyperparathyroidism can be a complex task. In some instances, diagnostic uncertainty remains despite detailed biochemical and radiological assessment. This paper outlines our approach to maximising the cure rate at primary surgery.
